How to Compress Files to the Max

To compress files as much as you can, use a high-compression rate archive format such as 7Z. High compression archive formats like 7Z can take much longer to both compress and decompress, but the rate of compression is higher than simpler formats like ZIP. This means your file will become even smaller once it's compressed to the max amount. The native program for 7Z is 7-zip.
